Tracking the motion of charges in a terahertz light field by femtosecond X-ray diffraction.
In condensed matter, light propagation near resonances is described in terms of polaritons, electro-mechanical excitations in which the time-dependent electric field is coupled to the oscillation of charged masses. This description underpins our understanding of the macroscopic optical properties of...
